Pandas split column into multiple columns by comma

Pandas split column into multiple columns by comma

To split a single column into multiple columns based on a delimiter (like a comma) in pandas, you can use the .str.split() method. Here's how you can achieve this:

import pandas as pd # Sample data data = {'column_to_split': ['apple,banana', 'orange,grape', 'kiwi,pineapple']} # Create a DataFrame df = pd.DataFrame(data) # Split the column and expand into new columns df[['column1', 'column2']] = df['column_to_split'].str.split(',', expand=True) print(df)

In this example, the .str.split() method splits the values in the 'column_to_split' column using the comma as the delimiter. The expand=True argument indicates that the result should be expanded into new columns. You can replace 'column1' and 'column2' with the desired column names.

The output will be:

 column_to_split column1 column2 0 apple,banana apple banana 1 orange,grape orange grape 2 kiwi,pineapple kiwi pineapple

This creates a DataFrame with the original column and the newly split columns. Make sure to adjust the number of new columns you create based on the number of values you expect after splitting. If you have more than two values, you would need to create additional columns accordingly.
